CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 285,507, datedSeptember 25, 1883.

I Application filcd February 10,1883. (No model.) i i To @ZZ whom it mayconcern:

Be it known that I, J. CURTIS PATTERSON, a citizen of the United States,and a resident of the city and county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Oar-Brakes,of which the following is a specification.

My invention relates, in general, to improvements in that kind ofcar-brakes in which the brake-shoe is applied directly to the rail, in-

stead of to the wheel of the car, andmore particularly to improvementsin Letters Patent No. 271,111, granted me January 23, 1888.

In the accompanying drawings, forming part of this specification, and inwhich similar letters of reference indicate like parts throughout theseveral views, Figure 1 represents a side view of a car-truck embodyingmy invention; Fig. 2, an enlarged side view of my invention; Fig. 3, aside view of my invention when but one shoe is used; Fig. 4, a side viewof one of my brake-shoes, and Fig. 5 a top view of the same.

The brake-shoes A, whichbear directly upon the rails, are operated by apair of toggle-1e 'vers, B C, so arranged that they form a parallelmotion, and the shoe has at its end or ends a projecting pin, D, whichtravels up and down in a slot in the bracket E, which supports andguides the shoes.

The levers B and O, which are secured to some convenient place on theframing of the truck, are coupled together by a link, F, and motion isimparted to these levers by a link, G, one end of which is secured tothe pin which secures the levers B and link F togetlr er, and the otheris secured to the end of a Fig. 3 represents a side view of my inventionwhen but one shoe is used. In this case the shoe is considerably longerthan is the case when two are employed, and the togglelevers N O areboth secured to the same shoe, and their action will be clearlyunderstood from the drawings.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. The combination, in a car-brake, of the shoe A, leversB G, arms F and G, and crank H, the whole arranged and operatingsubstantially as and for the purposes described.

2. The combination, in a car-brake, of the shoes A, operated bytoggle-levers B O, and brackets E, secured together by a frame, M,

all substantially as and for the purposes set forth.
